top. The frame work of the tower is made of angle-iron. An engine or motorV is em- 1 ployed to drive a winding-drum, and a cable connected to the car and said drum is ernployed to raise lower the car.

The walls and bottom of the pit have a sheet-metal lining 1S; the frame-work l1,

` of the tower includes standards, cross-bars,

braces and plates as shown in the drawing but the particulai1 construction of the tower rThe coaldumping car 12, is rectangular in plan, as seen in Fig. 3, and in moving up and down within the tower this car is guided by two stationary vertical bars 14, which are attached yat opposite sides of the'tower; these vertical guide bars` 111, extend from the pit 10,'to a point above the cross-bar28, near the top of the tower. Two exterior sides of the car are provided with specially constructed grooved guide blocks 15, 16, that `cooperate with the said stationary vertical guide bars 14; the uppermost grooved block 15, is secured rigidly to the exterior' side of the car 12, see Figs. 6 and 7; this upper block is stationary and its groove extends in a vertical position when the car-body has its normal horizontal position'. A second grooved guide-block 16, is pivotally secured to the exterior side of they car below the`r said uppermost block 15; this lower grooved block is secured tothe side of the car by a Vscrew or bolt 46, placed intermediate the two ends of-the block and serving as a pivot,

whereby the car ymay tilt to dump its load of` coal while the lower guide-block 16, remains vertical withv its groovel engaging the stationary guide bar 14, as in Fig. 6. When the said car is moving up or down, the grooves of the two guide-blocks 15,16, are in true Vvertical alinement with .each other, as in Fig.

7, and. of course .during such up-and-down i movement the grooves of both blocks will be engaging-and sliding along the vsaid guide bar 14. But whenthe coal-dumping car 12,

at time of going up reaches its highest point of elevation, the two Y uppermost grooved blocks 15, willpass above the vtop ends 14a,

`of the two-guide 'bars-14,' and thereby disengage from said guide bars, and at the same time of such disengagemenna stud 1'?, fixed on each side of. the car near its front end and'projectingv laterally from the car-side, will strike against a laterally-projecting pin 18, that is rigidly fixed to the frameworkof filled, the engine 25, would be started and Y the tower 11.1T-wo such stopipins 18,.are

used, one being on the tower at a side oppov site the other; these two fixed pins on the tower are in the path` of theV upward movement of the two studs 17, on opposite sides of the car. Nhen the studpins on the car atthe time of moving upward, strike against the two stop pins 18,011 the tower, the front end 19,01? the car ceasesto moveup, but therear end 12, of `thefcar will lcontinue to be raisedfwith the efl'ect of tilting down Ythe 'front end'of thecar as in thebroken lines 1n Flg. 1, to causethe coal in the car to slide' The front end 19, of the car 12, is `no1'-V mally closed by a hinged wall 20, each of whose two ends carry fa quadrant-shaped plate 21; this structure servesas a wall and e also as a tilting chute to discharge the. coal.

- the car-bottom 23. n Fig. 1, the dumping v car 12, is shown in full lines at the bottom ofY The wall 20, Vhas hinges 22,`that,secure it to the pit, and the car is alsoshown in broken lines in tilted'position near the top of the The operation ofthis dump-ear and tiltving chute would be as? follows: Theempty car being at the bottom'of the.pit ,ras in Fig.y

1, willbe loaded withv coal passing over the pivoted chute 24.;A when the car has been the cables 26, would lift the'car. As the car moves upward the top edge of thehinged wall 20, will be pressed outwardly'by the coal'in the car and said top-edge will slide J along in contact with the vertical vbar 27, at-

Y tached to the tower; the upper end Yof this bar 27, terminates at thev crossbar 28. Just before `the stud-pinsl?, onV the car strike against the stop-pins 18, the hinged wall 20, l

of the car front will pass above the cross-bar 28, of the'tower and'saidhinged wall with itsquadrant plates 21, will then 'tilt o-utward through the open spaces in the frame-work of the tower, as indicated by brokenV lines in Fig.' 1; in this outward positionthe said :hinged -wall and yquadrantplates 21, willl serve as a-chuteto discharge'the coal from the car Vdown( into the tender 29, shown in Fig. 1. As 'soon as the "coal has been 'dumped from the eleva-ted car into the-tender, the man in charge will reverse theengine and allow the empty car to begin todescend; the hinged wall 20, of the car which has been projecting outward, will .be tiltedbackinwardly to its closed position by the car descending-while said hingedwall is dragging back over the said cross-bar 28.l

As already explained, thelcar-tr'ack 9, on

which the locomotives and tenders approach the coal-toweri11, extends along one side of said tower, see'Figs. 1 and 3,1and`the1cartracks 30,011 which the loaded hopper .cars

a vertically-sliding 'doorn 311, slides up and down in, a guide-way 35, at the lower-end of l' ksaid incline and at the wall or Vli'ning"1 ,fof the Y pit. A hinged chute 241, takes'either one of two positions whichare determined by the position of the said verticaldoor 311, A

This inclined bottom 42, facilitates the dis-r charge of coal. l The car has at the center of its top edges a grooved roller 44, andv at its front end 19, a metal strap 45, with an eye.; the lifting cable 26, ytakes under the said roller 44, and then extends forward horizontally along the top edge of the car-side and is secured to said eye in the strap 45.

Having thus described my invention what I claim is,-

l. In a tender coal-loading apparatus, the combination of a tower provided with two stationary guide-bars attached at opposite sides; a pit in the ground below the bottoni of the tower; a downward inclined opening 33, at one side of the tower and leading from the surface to said pit; a vertically sliding door at the lower end o said downward incline; a chute 24, hinged to said incline and adapted to tiltv downward when the door is op'enyand project into the pit, and also adapted. to turn upward and take position in the space of said incline when the door is closed; and a coal-dumping car movable np and down within the pit and tower and said car automatically raising and lowering said vertical sliding door by said movements.

2. In an apparatus for supplying tenders with coal, the combination of a tower provided with two guide-bars extending vertically from the base to a point above the cross bar Q8, near the top of the tower; two laterally projecting pins 18, on the tower at its dumping side; a coal-dumping car vertically movable within the tower and opposite sides of said car provided nearits front end with laterally-projecting studs 17, which on the up movement of the car strike Vagainst said lateral pins and tilt the car, and said car also provided with a'grooved guideblocl l5, rigidly secured to the car-side, a second grooved guide-block pivotally secured to the car-sides below said rigidly-secured block, and as the oar moves upward the grooves of both upper and lower blocks engaging said side-bars to the top end of the latter where the said upperrnost blocks will disengage from the guide bars but leaving the pivoted guide block engaged, thus the car is automatically tilted and its load dumped through the side of the tower while the pivoted block Vremains engaged with the guide-bar.
